analysis algorithm, the principle and the Microsoft Neural Network analysis algorithm, just like the focus is not the same, the Microsoft Neural Network algorithm is based on a certain purpose, using the existing data for " probing" analysis, focusing on analysis, The Micro

Because this is the first complete data analysis, there will be a little sense of accomplishment after completion. below is my final data comparison: although you have occasionally used tools or logs to analyze website data Because this is the first complete data

Abstract: Data analysis has become indispensable, and almost every company relies on data analysis for decision-making. In my online gaming field, data analysis is one of the most important means to plan new functions and optimi

predictable, the algorithm generates a separate decision tree for each predictable column.The principle of the algorithm:The Microsoft decision tree algorithm generates a data mining model by creating a series of splits in the tree. These splits are represented as "nodes". Whenever an input column is found to be closely related to a predictable column, the algorithm adds a node to the model. The algorithm determines how the split is divided, primaril

(such as young, middle-aged, or old. In this form of data reduction, we will discuss the use of data discretization technology, where numerical data will automatically generate a conceptual hierarchy. Why data preprocessing? Imagine that you are the manager of allelectronics, responsible for analyzing the company sa

Introduction to Application Background In many typical industry applications, data that is generated and maintained according to geography, time, or category dimensions is needed. The managed data classification is maintained in a constant manner, while the content (field) of the data itself needs to evolve according to the business needs. On the one hand, the

Often have friends ask the author, SEO How to get started, the author is accustomed to say will send outside the chain, will change friendship has already counted the entry-level SEO, certainly have a friend will ask how can become SEO master? Today we will tell you some of those high-level SEO is good at the site data analysis. The author also found on the Web site dat
